Yeah that does happen on occasion. But there were a couple of other interesting quirks I ran into...

1) There was a case where I pushed the balloon down. WAY DOWN... like it went past the bottom of the screen and then came back to the top of the screen, went all the way down to the bottom of THAT, then a third screen before finally coming up... which took a while if you could imagine. Naturally, I didn't submit that recording.

2) There was another case... I don't remember exactly what happened, but the main music kept going even as the clear bonus screen came up. Then I think the clear music finally started, but after about 8 notes, the next stage was about to begin... now THERE is weird.
